Monsanto officials limited dicamba weedkiller testing, court testimony shows

Knowing federal regulators were paying attention to the new weedkiller's potential to contaminate other fields, Monsanto decided to “pull back” on testing to allow dicamba, according to testimony in the federal trial over the weedkiller. Bader Farms, the largest peach farm in the state, alleges that dicamba damaged their orchard.

Dicamba revisited: Will corn be the next herbicide debacle?

Dicamba-tolerant corn seeds aren’t available yet. But if the seeds reach the market, and tens of millions more acres are sprayed with dicamba, there’s good reason to expect a repeat of the soybean disaster, in which the highly volatile weedkiller drifted off-target and damaged 5 million acres of conventional soybeans and an untold number of other crops.<strong>(No paywall)</strong>

Dicamba has sparked a civil war in soybean country

The controversial weedkiller dicamba, which has wreaked havoc in soybean country over the last two years, is dividing communities and pitting neighbor against neighbor as the 2019 growing season gets underway. FERN's latest story, a radio piece produced with Reveal and the podcast Us & Them, takes listeners inside these divided communities in Arkansas.<strong>(No paywall)</strong>

Pigweed develops resistance to dicamba and 2,4-D

Researchers at Kansas State University have found pigweed that tolerates dicamba and 2,4-D, two herbicides that are often used to combat the invasive weed. Pigweed, or Palmer amaranth, is difficult for farmers to control, growing up to 10 feet tall and capable of producing 1 million seeds per plant.

Arkansas approves expanded dicamba use, dismissing scientific and public concerns

Arkansas regulators voted on Wednesday to relax restrictions on the controversial weedkiller dicamba, despite testimony from top scientists and scores of concerned citizens who urged them to reject the move in a public hearing. <strong>(No paywall)</strong>

Dicamba debacle spreads to bees

The weedkiller dicamba, which has spurred conflict in farm country because of its damage to non-GMO crops, has spread to beekeepers, who say the herbicide is depleting pollinator habitat and harming the bees, according to FERN's latest story produced in collaboration with Reveal from the Center for Investigative Reporting.

Court challenge to EPA approval of dicamba is dismissed as moot

A federal appeals court on the West Coast dismissed as moot a lawsuit by environmentalists to overturn the EPA's 2016 approval of the weedkiller dicamba. The Ninth Circuit U.S. Court of Appeals said the environmental groups could try again with a challenge to EPA's reapproval of the herbicide last November. <strong>(No paywall)</strong>

Opposition mounts as Arkansas moves to roll back dicamba ban

The Arkansas State Plant Board voted to roll back restrictions on the drift-prone herbicide dicamba late last week, over the objections of a coalition of sustainable agriculture and conservation groups. The board denied, without a hearing, an organic farmer’s petition to uphold the restrictions.

FERN/Reveal investigation shows EPA ignored decades of science on dicamba drift

A new investigation by FERN and Reveal, from the Center for Investigative Journalism, shows that the EPA "ignored scientists’ warnings and extensive research that showed dicamba would evaporate into the air and ruin crops miles away, according to documents obtained through public records requests and lawsuits. Instead, the EPA’s approval was based on studies by the companies that manufacture dicamba, which independent scientists say were seriously flawed." <strong>(No paywall)</strong>

Fighting dicamba damage in Arkansas

After nearly 1,000 complaints from neighbors about damage from the weedkiller dicamba, the Arkansas State Plant Board banned use of the herbicide on soybeans and cotton during the growing season this year. Yet state officials still are receiving complaints about dicamba, especially in the northeastern corner of the state, near the Missouri border, says NPR's The Salt, and the state is looking for the culprits.

State regulators call for early cutoff date for dicamba use

Many states have reported significant complaints from farmers about dicamba damage to their crops and plants, said an association of state pesticide regulators in calling for the EPA to tighten its rules on use of the weedkiller.

Groups ask appeals court to take dicamba off the market

Environmental groups told a U.S. appeals court on Wednesday that the EPA had failed to properly assess the risks posed by the weedkiller dicamba to nearby crops and should be ordered to revoke its approval of Monsanto’s version of the herbicide, reported Reuters.

Dicamba takes a toll again on neighboring fields, say weed specialists

Monsanto proudly says its low-volatility formulations of dicamba, coupled with cotton and soybean varieties genetically modified to tolerate doses of the herbicide, is an effective tool against invasive weeds. But weed scientists report that damage to neighboring fields and susceptible nearby crops is a recurring problem this year. "I have never seen a herbicide that has so easily and frequently slipped the leash," wrote Tennessee weed scientist Larry Steckel in Delta Farm Press.

EPA should set a lower application rate for dicamba, says North Dakota official

Doug Goehring, the state agriculture commissioner in North Dakota, says "90 percent of the problems with off-target movement" of dicamba "may go away" if regulators set a lower application rate for the herbicide. In an interview, Goehring told the Capital Journal that he might allow a lower application rate for crops in his state even if EPA does not revise its rules for the controversial chemical.

Class-action suit targets dicamba, Monsanto and BASF

A class-action lawsuit filed in U.S. district court in St. Louis says Monsanto and BASF genetically engineered dicamba-resistant crops knowing the weedkiller was likely to harm neighboring crops, and that "everything they did and failed to do increased the risk," reports Harvest Public Media.

Despite tighter rules, dicamba damages 1.1 million acres of soybeans – report

University weed scientists estimate at least 1.2 percent of U.S. soybean plantings have been damaged accidentally by the weedkiller dicamba despite stricter limits on its use this year, said a University of Missouri report. Damage was highest in Illinois, the No. 1 soybean-growing state, where 500,000 acres of the U.S. total of 1.1 million damaged acres are located. Arkansas was second with 300,000 damaged acres.

Dicamba weedkiller damages nearly 384,000 acres of soybeans

Weed scientist: When will agriculture hit the reboot key?

“Off-target” herbicides are creating tremendous discord in farm country, writes weed scientist Ford Baldwin in an essay for Delta Farm Press, adding that “dicamba technology has been the most divisive of my career.”

EPA order allows sale and use of existing stocks of dicamba

Retailers are allowed to sell and farmers are allowed to use existing stocks of the weedkiller dicamba on this year’s soybean and cotton crops no later than July 30, said the EPA on Wednesday. A federal judge in Arizona overturned the EPA’s approval of three dicamba-containing herbicides last week, potentially disrupting the spring planting season.
